[jira] [Commented] (OLINGO-76) @MappedSuperclass

["Chandan V.A (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/OLINGO-76?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13848412#comment-13848412 ] 

Chandan V.A commented on OLINGO-76:
-----------------------------------

Hi Thiago,
The java reflection method getField( ) cannot access the private member variables defined in the super class.

If the field is could not be found then there should be a fallback mechanism to search for the fields type using its public modifier method namely "getXyz( )". I will try this.

regards
Chandan

> When i use @MappedSuperclass i got the error below:
> Caused by: java.lang.NoSuchFieldException: creationDate

> 	... 75 more
> I suppose this is an error because the method olingo.odata2.processor.core.jpa.access.model.JPATypeConvertor.convertToEdmSimpleType should not use getDeclaredField (), but getFields () to search also the attributes of the parent class.
